ABSTRACT:
A tape applying apparatus to advance, cutoff, and transport two or more adhesive covered tape strips and apply same to a continuously moving series of connected diapers before the diapers are cut into discreet products; the apparatus being arranged so that the distance between two consecutive tapes is different from the distance between two other tapes, and all tapes so applied will be cut at equal lengths; and since different spacing requires different tape feed speeds, the invention includes two tension isolating and feed roll pairs arranged to allow an excess of tape to be looped therebetween, including loop detection devices which rotate the first and second tension isolating roll pairs at different speeds to maintain said loop of excess material within predetermined minimum and maximum limits.
